Specification of Letters Patent.

Patented April 14, 1908.

Application filed March 18, 1907. Serial No. 362,802.

To all whom it may concern:

Be it known that I, WILLIAM J. UEBLER, of town of Schuyler, in the county of Herkimer' and State of New York, have invented certain new and useful Im rovements in Milking-Machines; and I do ereby declare that the following is a full, clear, and exact description thereof, which will enable others skille in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The object of my invention is to provide a milking machine embodyin certain im provements and features 0% construction which make it eflicient and desirable, and which are of that simple construction which enable the machine to be repaired and maintained, as to its necessarily removable parts, cheaply and expeditiously.

Figure 1 is a plan view of the set of teat cups with certain parts of the connecting tu es and their appurtenances shown in section. Fig. 2 is a side elevation in art of a set of teat cups and in parta vertica section of a teat cup and of the connecting tubes and The sectional portion of this figure is taken on line AB of Fig. 1. Fig. 3 is a sectional detail of the teat cup taken on line CD of Fi 1. Fig.3 is another sectional detail 0 the teat cup.

Fig. 4 is a plan view of the receiving recep-,.

tacle cover with certain details of the mechanism shown in horizontal section. Fig. 5 is a vertical sectional view of the top of the receiver receptacle, the receiver cover and of certain mechanical parts mounted thereon, the section being taken on line wa: of Fi 4. Fig. 5 is a partial section taken on gine z2 of Fi 5. 'Fig. 6 shows a vertical section, and igs. 7, 7 and 7 show a horizontal section of a regulating stop cock employed in the construction in various positions which it is adapted to assume. Fig. 8 shows a vertical section of the receiver cover and the mechanism mounted thereon taken on line 2 of Fig. 4. Figs. 8, 8 and 8 show detailsof a filtering or screening device, which may be employed in the construction.

Referring to the reference letters and figures in a more particular description, 1 indicates the body of the teat cup which is preferably of thin sheet metal and in the -u permost of these main of a cylinder'shell form, havinginternal encircling ribs 2, 3, 4 and 5 s aced at suitable the lower end of the teat cup body and held by the rib 5 as a shoulder on one side, and the lining is secured by the cap 6 which is screwthreaded into the lower end and grips the lining and ring 8 between the cap and the rib 5. The upper end of the lining 7 is folded over the upper edge of the teat cup body, which has a bead 1 at its edge, and down on the outer side where it is held firstby a spring band 9 and farther by the elastic mouthpiece 10.

The teat cups are provided in a set of four connected to a common means for operating the same. At the side each teat cup is provided with a section of tube 11" connecting with the space'between the body and the lining 7 by four ports, 12, 13, 14 and 15. The ports is located just a ove the internal rib 2, while the other three open into the depressions between the internal ribs 2, 3, 4 and 5. The three ports 13, 14 and 15 are rovided with spring pressed valves 16, wiiich close these ports against fluid passing inwardly, but ermit the open-, ing for outward assage. Each teat cup is also provided wit one or more manually operatable vent cocks 17. v

For each set of teat cups there is provided a common junction and controlling device, consisting in the main of body 20, having two chambers 20"* and 20 and four stub tubes 21, 21, 21, 21, connecting with the chamber 20* and four stub tubes 22,22, 22, 22, connecting with chamber 20'. The stub tubes 21 are connected with the lower ends of the tubes 11 res ectively by sections 23 of flexible tube, and the stub tubes 22 are connected with the nipples 6* respectively on the lower ends of the teat cups by sections of flexible tube 24. From the chambers 20 and 20 respectively lead tubes 24 and 25 To regulate or entirely close the passages through the tubes 21 and 22, a stop cook 26 of a peculiar constructionis employed. This consists of a socket having a' conical opening to receive the plug part, together with a supplemental opening 26*. he revoluble plug part 26 has assage ways-a, b and c, the first extending iametrically through the plug, the second extendin from the lpassage a radially through one wal and the t ird extending in an upwardly and outwardly direction through the other wall from the passage a. The passage a is of the full capacity of the tube, while I) and c are much reduced and the latter is adapted to re ister with the supplementalopemng 26 on y. s

For controlling the ressure and facilitating the operation of t e teat cups, there is provided a manually and automatically 0 ening valve 33 and piston 29 therefor. T lie piston is arranged in a cylinder 30 in the u per art of the body 20 and the space a ove t e piston is placed in communication with the space below the cylinder by the passage ways 31. The iston in addition to carryin'g the valve 33 a so has a stem 32 which passes through the head 28 and carries a spring 34, an is provided with an adjustable knob 35 confinin and compressing the s ring 34 between itsef and the casing hea 28. The head 28 has inlet openings or assages therethrough, which are controlle by the valve 33. The cylinder beneath the piston 29 is placed in communication with chamber 20 by the passage shown, and the piston is provided adjacent to the topwith an encir ling groove adapted to re ister with the drain passage to the exterior s own.

For controlling the operation of the teat cups and their mechanism described, there is rovided a pulsator and regulating mechane ism, which, with its appurtenances, may now be described. The mechanism is preferably mounted on the cover 40 of the milk receiving receptacle 41, which cover is adapted to close the receptacle particularly against the entrance of external air when a vacuum is created in the receptacle or the pressure therein reduced below normal atmospheric pressure.

I The pulsator embodies in the main two automatic piston .valve mechanisms, 42 and 43, together with suitable chambers for containing these valves and suitable ports and passage ways in connection therewith. The valve 42 controls directly by 0 crating in connection with the ort 44 t e fluid or as used in operating the pressure side of t e ap aratus, the same being connected throu the pipes 45 and a suitable piece of flexl 1e tubing with the chamber 20 before mentioned. This valve 42 also serves to control the application of suction to the pressure side of the teat mechanism; also throu h the tubes before mentioned and the cham er 20.

Fluid under ressure or compressed air or gas is supplied om a suitable compressor to the cylinder containing t the pulsator through the tube 46, while the pulsator is also p aced in communication with a suitable suction or vacuum creating mechanism or apparatus throu h the medium of tube 47. The fluid un or pressure is sup lied through the ipe 46 to two ports 48 an 49 in one side of t e cylinder 0 emng, which receives the valve 42, while t e suction or vacuum side is also connected with this cylindrical o ing through a port 50. The valve42whi e being of a .eneral cylindrical form, having particular y the heads 42 at'either end closely fitting the cylindrical opening, in which the valve is located, conslsts more particularly of a series of walls dividing the valve into chambers d, e, f, g

and h. The chamber (1 is placed in communication with the chamber h by an opening '5, while the chamber f is placed in communication with the chamber 9 by an opening k.

In order to prevent the valve 42 from rotating on its own axis in the cylindrical opening, in which it is contained and still permit it to have its free longitudinal reciprocating motion, there is provided in the upper edge of the valve a longitudinal groove 42*, which receives the inwardl pro ecting end of a screw or in 42. T ere 1s -rovided for controllin t e size of the availa 1e opening .through t e port 49 an adjustable valve provided on the end of screw 49.

The valve body 43 has two cylindrical portions 43*, 43, which are the valves proper,

and control circular ports 51, 51 and 52, 52 provided in cylindrical openings in the pulsator body. It is also provided with piston eads 53, 53 at either end arranged in cylinders respectively in the pulsator body. The port 51 .is the terminus of a branch of pressure supply pipe 46, while ports 52 connect by passages 54 respective} with the ends of e valve 42. An exhaust chamber 55 is provided with a port 56 and is connected by a tube 57 connecting with a muffler 58 located on the cover 40. The cylinders containing the pistons 53 and valve 42 are placed in communication by passa es 60. he end of the passage at the cylin er containing the valve 43 is adapted to register with the chamber e in the valve 42, while the end of the passage 60 in the cylinders containing the pistons 53 is at the outer side of the piston 53 when in its outer osition. Bumpers 61 are provided for imiting the movement of the valve body 43 with its appurtenances in each direction, and these bumpers are provided on push buttons 62 extending through suitable stuffing boxes, whereby movement can be given manually to the valve body 43.

The suction pipe 47 is also placed in communication with the interior of the recep tacle through the medium of the tube 65 and the chamber 66, which contains a spring -tion pump or apparatus,

f of valve 42, opening o I i l 1'- 884,78! 1 a pressed regulating valve with means for adjustin the tension of the sprin consisting of' t e screw 68 -and the loc nut 69. The tubes 45 on the receptacle cover are connected by flexible tubes 24 with stub tubes 24 mentioned. The stub tube 25 is connected by means of a section of flexible tube 25" with a ri 'd section of tube 67 provided on the hea 40 of the receptacle, which furnishes an inlet openin through the head 40. This section 67 wil? preferably include a glass tube portion 67*, through which the flow of the milk may beobserved, and a stop cock 67 for controlling the passage. he sections of tube 45 before mentioned will also preferably. be provided with stop cocks 45*. Two or more sets of teat cu s may be connected with the same receptacl Means for making connection with two sets of teatcups are shown in Fig; 4.

The operation of the device may be briefly described as follows. The pipe 46 being connected with somesuitable source of su ply of fluid or air under ressure and the tu e 47 being connected wit some suitable sucthe teat cups are a pliedin'the-usual and obvious manner. The suction through the pipe 47 exhausts or rarefies the air in the receptacle 41 and the degree of rarefaction may be regulated by ad usting the pressure of the spring on the valve 70. A suction is applie to the teat in the teat cup through the medium of the tube 25, and the connections heretofore described, to the nipple 6 at the lower end of the teat cup. During the-time that the valve 42 is in the left-hand end of its cylinder, as shown in Fig. 5, the pressure from ipe 46 is communicated throu h ort 49, c amber f the same, chamber g of the same, to ort 44, from which communication'is estab ished through tube 24* withthe tube 11, and thence through the ort 12 to the space between the teat cup body and the lining 7.

It will be noted that the pressure is introduced first at the upper end of'the lining, and as the inflation adually takes place the lining is peeled ofl so to speak, from the rojecting side of rib 2 until the air or fluid is ada ted to enter the space between ribs 2 and 3, w en a continuation of the inflation gradually fills this space until the lining is peeled off from the to of rib 3 and the operation is continued unti a full inflation has been ac complished'. Thus the operation is to squeeze the up erportion of t e teat tightly and gradua-y continue the pressure ongitudinally down the teat until the lower end is reached, during all of which time a suction is maintained on the lower end of the teat. An interval of time for the inflation of the lining is provided in the movement of the valve 42 to and fro through a half of its throu h struction is shown in substantially so,

the opposite direction.

stroke in its cylinder. There is also a certain neutral period during the time that the effective valve face 44 of the valve 42 is passing over the port 44. When this valve ace has passed t e port 44 and the port is put in communication with the chamber h, the ressure is cut ofl from the s ace between the lining and the casing of tile teat cups, and a suction substituted therefor.

It will be noted that the space it is in communication throuh the o ening i with the space d'of the vs vs 42, w ich 1n turn is in communication with the suction apparatus. In exhausting the contents of the space between the lining7 and the shell of the teat cup, the fluids may pass outwardly throu h the four ports, 12, 13, 14 and 15 into t.e pipe 11. Thus the space may be quickly emptied, and, further than that, the lining between the several ribs brought Well back into the space between the ribs.

An interval of time for the exhaustin operation, as before described, is provided in the movement of the valve 42 to and fro the other-half of its movement in the rightand end of its cylinder as the consure from the pipe 46 is also utilized to move thevalve 42 alternatively in one direction and then the other. This movement is controlled by the valve mechanism generally designated as 43'. As the parts are shown in Fig. 5, it will be noted that the pressure is bein taken through the ort 51 on the lefthanf end; thence around the body of the valve 43, and, enterin the chamber which receives the piston head 53, passes through a port into passage 54 and thus enters the cylinder containing the valve 42 at the lefthand end. The ressure accumulating in this end of the cylinder will cause the valve 42 to move to the right. When it has reached the right-hand end of the cylinder or the end of passage way 60 will be e of va Va 42, which also being supplied with fluid pressure the fluid passes into the s ace between the head of .the c linder and t e piston 53 on the right-hand o the pulsator, forcing the valve 43 with all its connecteddparts to a left-hand position. When this is one, it closes the port 51 on the left-hand end and opens the port 51 on the right-hand end, allowing the fluid pressure to operate on the right-hand end of the valve 42 to move it in An exhaust assage from one or the other end of the cylindbr containing the valve 42 is always provided for through the passage 54, and the port 56 which surrounds a reduced portion of the valve 43; thence to chamber 55, the exhaust pipe 57 and the muffler 58. In case the va ve 43 should become displaced into a neutral position intermediate of its normal Fig. 5. The fluid presut in communication with chamber stationary pplslitions, it can be put into mo-- tion by pus g the same by means of one or the other push buttons 62. It will also be noted that the arran ement is such that the movement of the vafive 43 is cushioned at either end of the stroke by the pressure which it controls.

The speed with which the pulsator will operate can be regulated either by means 0 the general stop cock 46 or the minor stop cocks 46 provided in the branches of pp y latter. teat cups will be by opening or valve 49. A variation in the operation of the teat cups even of the same set may be effected b operating the regulating cocks 26. It w' 1 be noted that when these cocks 26 are placed in the position shown in Fig. 6 that they are much reduced in their carrymg capacity, which accordingly slows up the operation. Sometimes this may be deslrable on the pressure side and sometimes on the suction side and sometimes both. This provides facility for adapting the machine to hard and easy milking teats and also to long and short teats.

One or more of theteat cups of a set may also be cut entirely out of operation by turning the cocks 26 to their cut off position. The effective suction pressure at each set of teat cups is automatically regulated by adjusting the tension of the spring 34. If this spring 34 is adjusted to a low tension, if the suction increases, it operates on the piston 29 to open thevalve 33, and relieve the situation same fluid he force and speed with whic the I. by letting air into the tubes and mechanism.

In case t e spring 34 is placed under greater tension, a hi her rarefaction may be attained before t 's safety valve device will- 01p- .erate. This mechanism consisting of valve 33 and its connecting parts is also useful for manual operation in relieving the suc-.

tion when it is desired to remove the teat cup from the teat, and is also useful for providing an intake of air to blow out the milk in the tubes 25 and enable it to reach the receivhe e astic mouthpiece 10 provided at the per end of-the teat cu s enables cups to be fitted to teats more readi y of somewhat varying sizes and facilitates the teat cup being maintained in position on the teat b the suction a plied at the lower end. t will be noted that the mouthpiecelO ma be readily displaced from its position on t e teat cup and that the lining 7 may be readily removed and replaced in case of necessity.

. The machine may also be operated entirely by suction if desired. To that end there is a port 75 provided between the exhaust chamingrrece tacle 41.

er 55 and the base of suction tube 47. This tus.

is used as a combination pressure and suction machine bythe set va ve 76. When the valve 76 is open a suction is applied to what would otherwise be the exhaust of the pressure side, and the atmos heric ressure is utilized to 0 erate both, si es of t e appara- In or er toprevent an intake of air through the exhaust pi e 57 there is provided in this pi e a stop 000 57 which must be closed w en the apparatus is operated by suction only.

-\'Z 5 The screen device shown in Figs. 8, 8 and.v

8 consists of a small chamber 80 filled with alternating sieves or screens 81 and rings 82. This screen device may be inserted between the sto cock 46 and the body of the pulsator an in case the device is emplo ed to op-' crate by suction only the stop coc 46 may be dispensed with.
